One person has been killed and several others injured on a Singapore Airlines flight from London that was hit by severe turbulence.
The Singapore-bound Boeing 777-300ER was diverted to Bangkok and landed at 15:45 local (08:00 GMT).
Flight SQ 321 was carrying a total of 211 passengers and 18 crew, the airline said in a statement.
On a general note, I believe both 787 and A350 do possess a scintillometer to measure CTA to some degree.
